I've been collecting these for several years with no specific project in mind, so it's time to let them go. This post covers the Twin Blues. To see Greenline or Deluxe gauges, check out the other 2 posts. Vacuum gauge in excellent, beautiful condition dated August 1960. I carefully pulled this one apart to lube the mechanism and to clean the face and glass. This was a really tough one to find- get it now before it's gone! SOLD Oil Pressure dated February 1964. The bezel has a minor split at 6 o'clock, and there is some dirt behind the glass. Overall still very nice. $40 shipped. Fuel pressure gauge dated September 1960. I have only seen one of these, and this is it. I probably overpaid for this, but oh well. When I got it, it was not working and was extremely dirty. I carefully pulled it apart to clean the glass and face, free and lubricate the mechanism, and make sure it works. It's not perfect, but it is presentable. $150 shipped. Electric (12v) water temp - I did not see a date code. I carefully pulled this one apart as it was filthy inside. It is very nice now, and the needle moves freely to the opposite side once inverted and should work great. $100 shipped. Mechanical water temp with capillary tube cut, dated October 1960. Face is oxidized - I carefully pulled this apart to make sure the mechanism was free and to clean it the best I could. I believe this one is probably good for display only due to the face, but mechanically I believe it could be restored. $40 shipped. Another mechanical water templates July 1964 in much better condition, but with another capillary tube cut. I didn't pull this apart because I believe it is a good candidate for rebuild, in which it will get pulled apart by the person repairing/restoring the gauge. $75 shipped 2 gauge panel - oil pressure and amps. Absolutely beautiful piece! I carefully pulled both gauges apart to clean and ensure good condition. $100 shipped. NOS 12v electric oil temperature. Beautiful condition with original box. $150 shipped.
